摘要：

An X-ray structure determination of {CyNC[N(SiMe3)(2)]NCy}Zr(CH2Ph)(3), crystallized from pentane, differs from the solid-state structure previously reported for the same compound crystallized from toluene. In contrast to the earlier report, we find no evidence for the presence of an eta(2) interaction in the solid state by X-ray crystallography or in, solution by means of H-1 or C-13 NMR spectroscopy.
